What occurs in the heart during the P-R interval? When the nerves to the heart are cut, the heart rate increases to about 100 contractions per minute. What does this increase indicate about regulation of the heart rate? Explain the cardiac conduction...
in which the body begins to pale. Pallor mortis occurs because blood stops moving through the capillaries, the smallest of the body’s blood vessels. This process is identical for all people, but it’s less immediately a...

The laws of physics dictate that a fluid or gas flowing in a tube will accelerate if that flow is constricted. When this occurs, the pressure of the fluid in the constricted area must decrease to conserve energy. The constriction in a tube is known as a venturi and the simultaneous increas...
Complications in veins – Formation of a clot or thrombosis often occurs in veins. When this clot travels through the blood, it causes an embolism, which basically obstructs the flow of blood to the heart, brain, lungs, etc. Complications in capillaries – A significant increase in the passage...
Edema is a common physiological response that occurs when the body swells in response to injury or inflammation. Learn more about the definition of edema, the pitting and non-pitting types of edema, and explore the causes and treatment of the condition. ...
The pulse occurs in the arterial and venous parts of the vascular system. The arterial pulse, i.e. flowing from the heart into the body, provides information about heart rate, heart rhythm andblood pressure, among other things. The venous pulse, i.e. flowing back to the heart, on the ...
Anastomosis occursin a few places of the hearteven though the coronary arteries are considered end arteries. One anastomosis is between the branches of the LAD from the LCA and the branches of the PDA from the RCA. Another one is between the RCA and the left circumflex artery in the coronar...
Depending on the artery and the location of the clot, a heart attack or stroke (which occurs when a blockage is located in an artery leading to the brain) may then occur. Are There Other Causes of Coronary Artery Disease? While atherosclerosis is by far and away its most common cause, ...
